. ally necessary for the carpenter to hold the jamb in position whilesecuring'it to the sill .5 and often the work is delayed on thataccount.

The object of my invention is to provide a sill and j ambs of suchconstruction that they can be easily and quickly joined together andheldin that position preliminary to the nailing operation.

,l A further object is to rovide a means for interlockin the sill an theabutting ends of the jam s in such a way that the parts tion beforenailing, and when secured together joints are formed which willthoroughly exclude air and moisture from the walls of-the building.

A further object is to provide a means for interlocking the sill andjambs of a window or door frame, which, while adding materially to theease of assembling the parts, and excluding the weather, will notincrease appreciable extent the cost of manufacturing.

Other objects of he invention will appear from the following detaileddescription;

In the accompanying drawings forming part of this specification,

are firmly held in their proper relative posi- Figure 7 is a horizontalsectional view 1929. Serial 1%. 409,412.

Figure 9 shows a slightly modified form of sill composed of upper andlower sections', the view looking toward one side of the frame and theend of the sill.

In the drawing, 2 represents a window sill having the usual shoulders 3and 4:, the gains 5 formed at the ends of shoulder 4 and the projectingends or horns 6 forming continuations of the outer or forward portion ofthe sill. Adjacent these horns the sill is provided with the usualnotches or mortises 7 and between these notches and the rear edgeof thesill I provide similar notches 8. Across the ends of the sillintersecting the shoulder 3 and in alignment with the end walls of thenotches 8, I provide dados 9 forming transverse grooves in the uppersurface of the sill at each end, the cutting of these dados in the topsurface of the sill providing rectangular areas 10 at each end of thesill forming block like surfaces whose inner edges arein alignment withthe shoulder 3 and separated therefrom by the dados or rooves 9. Thesenotches and grooves are a l conveniently and rapidl formed by passingthe sill through a suitab e wood workin machine that is adapted for workof this character. 1

The j amb of the frame which may be either a window or door frame, theinvention being applicable to either, are indicated in the drawings byreference numerals 11, each jamb having on its inner face a verticalgroove 12 to receive a parting bead and provided on one edge with anarrow blind stop 13, having a sultable joint connection wit theadjacent edge of the jamb. The lower end of each j amb has a notch 14formed therein, extending approximately to a point near the verticalcenterof the jamb and between the notch 14 and the rear edge of the jamba depending tongue 14 is provided. The inner face of the jamb at thelower end is provided with a transverse recess or dado 15 which extendsentirely across the tongue 14 intersecting the horizontal edge of themortise 14 and forming at that point a transverse tongue 16 that isadapted to enter the dado 9 at the ends of the sill. The rear portion ofthe dado, or the portion thereof that is formed in the rear section ofthe jamb, is

adapted to receive the end of the sill that is in alignment with thedado 9. The vertical edge of the notch or mortise 14 butting the silland allow the jambs to stand vertically with respect to the sill. Beloweach dado 15 is a rib' or shoulder '17 forming the lower wall of therear portion of the dado and this shoulder will bear against the undersurface of the sill at the end thereof and aid in uiding the jamb to itsseat in the sill.

t is evident that when the notches or mortises and dados have beenproperly formed in the ends of the sill and the adjacent ends of thejambs and the parts assembled, they will stand in proper relation to oneanother without being held or otherwise supported and if the notches anddados are cut truly and of proper size, the j ambs will be held firmlyin vertical relation to the sill and be ready to be permanently securedto the sill by nails or other means, and during such operation it willnot be necessary for the carpenter or other person to support the sillor the j ambs. Furthermore, when the jambs and sills are assembled inthe manner specified, the joint between them will be so tortuous that itwill be practically impossible for air or moisture to enter the buildingwalls between the ends of the sill and the jambs and this improvement inthe construction of the window or door frame maybe accomplished withsubstantially the same amount of labor and machine work that is nownecessary to produce a sill and jamb of the ordinary description.

Figured of the drawing illustrates the appearance of the inner face ofthejamb when ready to receive the sill, a transverse notch or dado 18being provided at the upper end of the jambs to receive the ends of thehead jam v c o In Figure 6 the sill and jambs are shown in theirassembled relation with the tight fitting joints indicated between thelower ends of the jamb and the sill.

In Figure 7 a cross section of the jamb is shown illustratin itsposition with respect to the outside finish or casing 19 which, asshown, has one edge overlapping the blind stof) and concealing a portionof it.

11 Figure 8 the edge view illustrates the appearance of the assembledsill and jamb, the dados and grooves being indicated by dotted lines.

In Figure 9, a modification is shown in the form of the sill, consistingas shown, of an upper comparatively shallow section 20 and a lowerthicker forward. section 21. These parts are notched and grooved insubstantially the same manner as described with reference to theprevious figures and when assembled, the jambs are firmly held withrespect to the sill and may be conveniently and permanently securedthereto by nails or other means.

In this caseI claim a novel method of forming and assembling the silland jambs. This method consists in first notching the rear edge of thesill at each end andproviding a groove in the upper surface of the sillextending transversely thereof and forming substantially a continuationof the transverse face of each notch. I then notch the lower end of eachjamb at the forward edge thereof so that depending tongues are formed onthe rear portion of each jamb extending substantially from the rear edgeto the middle portion of the jamb. The inner face of each tongue isgrooved or recessed to receive the end of the sill, this groove beingcarried across the inner face of the transverse edge of the notch ineach jamb. This adapts the edge of the notch to enter the transversegroove in the upper surface of the sill while the tongue is firmlyseated in the notch in the rear edge of the sill and by forming thegains at the ends of the rear shoulder on the sill, I provide a seat forthe shoulder at the upper edge of the transverse groove which aids inholding the jamb and sill in their proper relative position.

This manner or method of forming and assembling the sill and jambsinsures a weather proof joint between the sill and the lower ends of thejambs and the carpenter having assembled the sill and jambs in this wayand without bracing or holding them, may nail or otherwise secure theinterlocking joints together and thereby form a permanent connectionbetween them.

This invention may be used in a window frame of the mullion type or in atriple or quadruple frame in which case the sill will be rovided withtransverse notches interme iate the ends in addition to the notch ateach end of the sill.
